Hi all, I have a data frame with sequences of x and y from a map. I would like to know it both ways: 1. How to make a matrix from that; 2. how to make a data frame of all points in a map. Probably it is a silly question, but please tell me where to read about it or tell me how to do it. Miha Staut

Hi all, I tried to produce some kriged surfaces with geoR (latest version). The size of the grid should be around 900 x 650 cells (what I find is not a very big grid), and the number of points is around 2500. The command krige.conv stopped after arround 5 min saying it can not allocate a vector with around 1.5 billion units. Sounds reasonable. Is there a workaround? How would I partition the

vector with a sequence starting from 1 to sum of all the values of the raster data and length(the same length as the sum). In another data frame (G) I have got a vector with the environment variables (G$xseq and G$yseq). How can I combine the x and y coordinates with tha raster data to form a data.frame? length(G$xseq)=3099 length(G$yseq)=5032 rastername=rst length(rst)=(3099*5032) Next question: I would like to broaden every unit in rst in the following way: rst2<-c(rep(rst[1:1], times=rst[1:1]), rep(rst[2...

Dear R support network I have a problem that is driving me crazy. I have a dataframe with about 74000 landscapes which I call "land". A landscape is a 2km -by- 2km square. Land has three columns: land$lat, land$long, and land$description. The last one holds a NON-unique (integer) description of each landscape. There are maybe 100 distinct descriptions. Identifying landscapes that

Dear R users, Does anyone have a function for putting a legend on an image plot? I couldn't locate an R equivalent of image.legend....has anyone written such a thing? kind regards andy --------------------------------------------------------------------- J.
